SYMPTOMS

Consider the following scenario. You have an application that may query a Windows 2000-based Active Directory. Then, during a long idle time the application does not query Active Directory. When the application tries to query Active Directory again after the long idle time, the application cannot retrieve information from Active Directory.

In this situation, you may receive various error messages that describe an authentication failure. The error messages may vary depending on the different applications that you use.

CAUSE

After a long idle time, the lightweight directory access protocol (LDAP) connection between the client computer and the domain controller will be automatically disconnected. The LDAP connection will be automatically re-connected when the client application queries Active Directory again.

In some specific scenarios, the wldap32.dll component will incorrectly delete the existing credential in the LDAP connection, when the LDAP connection is re-connected.
